Patented Aug. 1'7, 1909'. serial No. 363,315.

To all rwhom it may concern.

Be it known that I, FREDERICK C. MILLER, l

a citizen of the United Statesresiding at Cincinnati, in the county of Hamilton and State of Ohio,

Automobiles, of specification.

M v invention relates to an improvement in 'the construction of the' rear axle for @ne of the objects of the invention is to provide a gearcasing with a removable cap, detachable at the rear of the vehicle, the line of separation being in aV vertical plane, whereby the interior of the casing is rendered perfectly accessible and the gearing removable.

Another object of the invention relates to means for strengthening the axle and 'the gear casing relatively to one another.

The features of the invention will be more fully set forth in the description of the accompanying drawings, forming a part of.

this specification, in which Figure l is atop axle, showing the casing in horizontal scc- Vtion. Fig. 2 is a rear view` of the rear axle,

showing the gear casing in central vertical section. F ig. 3 is a fragmentary section of the casing.

l, 2, represent the opposite .end of the tubular rear axle.

3 represents a casing having the sleeves 4, 5,`into which the `tubular axle sections 1, 2, are respectively pressed, bra zed or otherwise secured.` The casing 3 is formed with an end-wise projecting stub sleeve G, into which extends the transmission shaft.

'T iepreseiits a cap forming a detachable section of the casing 3. formed on a vvertical line through the casing andat the rear of the axle, the cap beiiig preferably screw threaded into the stationary casing section. Byl this means, when the cap 7 is removed, the interior of the .casing is opened up, exposing and rendering perfectly accessible the interior mechanism fromA the rear of the vehicle, so that the parts 'canbe repaired or removed while the axle reniainsfattached to the vehicle triicl t`, -Without the necessity of reinovingthe body. The bearings housings in' the casing are formed by `thelixed nieiiibeis 8 to which the detachable caps 9 are bolted.

t10, l11, represent` the supports for the have invented certain new and useful improvements iii Rear Axles for plan view of the rear The (livision is springs, which may be sleeves pressed onto tl'ie axle, .or may be made in one with the axle.- -i

12, 13, represent rods, the outer ends of which are secured to the axle at l0, l1, and

the inner endsto the casing sleeve 6. These which the following is a rods lying -in a horizontal plane securely brace the front of the casing to the axle, (see Fig. l).

14,15, represent sleeves supporting the brake mechanism pressed or otherwise secured to the tube 1.

1 6, 17, represent a rod, the outer ends of which are connected to the sleeves 14, 15, the

Vnotched Gr.socketed into vthe bottom of the Preferably the rfod 16, 17, is couiicasing. tersunk into the bottom of the easing, as indicated in dotted flush withv the lower 4surface thereof, and hence the middle portion of said rod has the same road clearance as the bottoni of the casing.` This rod being sprung or bowed under the casing, o'ives great rigidity to the parts so reinforcet. vertical plane form another and a transverse brace between the casing and the axle, so

thatthe' axle and the `casing are securely tied together and protected against. strains in a vertical or horizontal plane, aswell as against all strains. This construction 1S extremely simple and strong, as well as 90 v compact. The provision of a section of the casing formed as a cap, ldetachable on a vertical line, makes it possible to `instantly open upthe casing giving complete access theretofrom the rear of the vehicle, Vwithout any further disineniberment of the organization, an element of'iininensc practical utility.

.0f course by stating that the rods extend in` horizontal and vertical approximately, as they may be slightly inclined thereto without materially changing the results.

Having described my invention, I claim 1. In combination' with/a, tubular -rear j axle of an automobile, a geareasing secured thereon, rods extending in a horizontal plane with their inner ends attached'to-the gear casing and their outer ends attached to the axle, and a. rod extending substantially in a vertical plane with -its outer ends-attached to the axle, and its intermediate portion lines, Fig. 2, so as to be These rods lying in a.

planes, I means 100 bowed under and socketed vn the bottoni of the casing, substantially as described.

2.v In u tubular axle for automobiles, agearcasng secured thereon, a-truss rod having its ends attached to the aX1e,' and its nfermedate portion bent under the casing,

Athe contacting portion of said rod belng countersunk n and socketed to the undersurface of sadcasng, substantially as described.

In testmonywhereof, I have hereunto set my hand.
